I don't think the drop-down will allow it (we validate quite strictly for domain names - might relax that in future).

You can do it by manually editing the organisation record in Mongo (edit your Org and change the CNAME to your IP) or using the admin API to modify the organisation CNAME record - both do the same thing and bypass validation.

It might work, but there's no real guarantee... because it may conflict with routing for the dashboard.

If you had an IP and a Hostname (e.g. someserver.mynetwork.somedomain.net - like Amazon AWS does with public DNS), it would work too.

You must set a host name for your portal using the steps described (click the drop-down, click "Set your portal domain"), you can try it with the host IP address but it might fail because of conflicts with the dashboard and it's not a valid host name. the hostname override that worked in v0.9.6 will not work for the portal anymore, this was mentioned in the upgrade notes.
